As Pete says a wee bit over cooked. Interesting, yesterday I was looking at postcards in a shop rack. They dated back to the 1980's. and sadly they looked really awful. It was after about this time that a few photographers took a newer look at holiday postcards in this area and did produce some reasonable images, often with a different slant, rather than the harbour view, it would be Cornish hedge rows or Cornish dry stone walls with the local plants, more abstract colourful images, so the subject matter did change dramatically.
Most of the post cards I noticed in the racks are sun bleached from being outside which gives them an old worldly look. Liking the postcard format which is why I often use the white border to replicate the look.
Nice one Brian.
